The heart of MatWeb is a searchable database of material data sheets, including property information on thermoplastic and thermoset polymers such as ABS, nylon, polycarbonate, polyester, polyethylene and polypropylene; metals such as aluminum, cobalt, copper, lead, magnesium, nickel, steel, superalloys, titanium and zinc alloys; ceramics; plus semiconductors, fibers, and other engineering materials. MatWeb is freely available and does not require registration. You can still access all of the features that have always been available. However, advanced features are only available to our Registered and Premium users

The NASA Scientific and Technical Information (STI) Programs mission is to collect, archive, and disseminate NASA aerospace information, and locate domestic and international STI pertinent to NASAs missions and Strategic Enterprises. Examples of NASAs STI include research reports, journal articles, conference and meeting papers, technical videos, mission-related operational documents, and preliminary data. NASAs technical information is available via the NASA Technical Report Server (NTRS) is to provide students, educators, and the public access to NASAs technical literature. NTRS also collects scientific and technical information from sites external to NASA to broaden the scope of information available to users. NTRSs Simple Search searches for NASA information only and its Advanced Search can search for NASA and non-NASA information. Most of the NASA information does not have full-text document images and documents can be ordered by contacting the NASA Center for AeroSpace Information.

The values of the constants provided at this site are recommended for international use by CODATA and are the latest available. Termed the ""1998 CODATA recommended values,"" they are generally recognized worldwide for use in all fields of science and technology. The values became available in July 1999 and replaced the 1986 CODATA set. They are based on all of the data available through 31 December 1998. A detailed description of the data and the analysis that led to these values may be found in the Journal of Physical and Chemical Reference Data, Vol. 28, No. 6, pp. 1713-1852, 1999 and in the Reviews of Modern Physics, Vol. 72, No. 2, pp. 351-495, 2000.

The Data Analysis BriefBook has been prepared by R.K.BOCK and W.KRISCHER
The Briefbook of Data Analysis, which is produced by staff at CERN, is an extended glossary or condensed handbook which covers the subjects of data analysis and statistics. It is intended to provide either an introduction or reference source for scientists and engineers. The briefbook consists of an index of statistical terms with definition and explanations.

The Electronic Statistics Textbook, produced by StatSoft Inc., offers training in the understanding and application of statistics.Chapters cover: elementary concepts, basic statistics, ANOVA/MANOVA, canonical analysis, classification trees, cluster analysis, correspondence analysis, data mining techniques, discriminant analysis, experimental design, factor analysis, graphical techniques, linear regression, log-linear analysis, multidimensional scaling, neural networks, nonlinear estimation, nonparametrics/distributions, process analysis, quality control charts, reliability/item analysis, SEPATH, survival analysis, time series/forecasting, and variance components. In addition, there is a glossary provided, together with a list of references.
